Abstract

Dominant species of Aoko, Anabaena, has a “function of nitrogen fixation from air”, so if
there is even phosphorus in water, they can multiplicate explosively. This study aimed the removal of
phosphorus by shells of regional unused resources as eutrophication countermeasure in Hasunuma Seaside
Park Pond. As result, sprinkling crushed shells was essential to the removal of phosphorus and the increase
control of phytoplankton such as Anabaena spiroides. Inhibition rate of phosphorus showed a high
percentage with much quantity of dispersion. At the N/P ratio, all dispersion system showed the higher value
in comparison with no-treated systems. Hardness showed a high percentage with much quantity of dispersion
because of Ca2+ was eluted into water from shell body. The dominant species of phytoplankton was changed
to Chlorella sp. and the growth of the phytoplankton was controlled until fifth or tenth day by Ca2+ eluted
from shells fragment.
